WebIncast occurs frequently in datacenter networks where a large number of senders send data to a single receiver simultaneously, which makes the last hop the network bottleneck. Incast can hurt flows' performance. However, congestion control protocols are not effective at handling incast. DAOS uses IV (incast variable) to share values and statuses among servers under a single IV namespace, which is organized as a tree. The tree root is called IV leader, and servers can either be leaves or non-leaves. Each server maintains its own IV cache. During fetch, if the local cache can not fulfill the request, it … See more The I/O Engine supports a module interface that allows to load server-side code on demand.
